Specification of Letters Patent.

Patented Sept. 23,1919;

Application filed June 7, 1918. semi Nb. 258,626.

To all wiio m a'ma oaoem- Be it linoivn that 1,,ALAN Cre mer, a citi- Zen of the United State s,.residing, in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Dumb-Bell, of which the follovving, is a specification.

y invention relates to improvement in an exercising device ofthe order of a dumb bell, bar bell, kettle bell, or the like,

and consists of a body of the device formed of plates, a casing therefor, a carrying. handle, and means on thehandle adapted to engage said body in. such' manner that said body and the handle are prevented from rotation one; on the other, and means for prleventing the plates from rotating on each ot er.

The invention is satisfactorily illustrated in the accompanying dravving,but the im portant instrumentalities thereof maybe varied, and so it is to be understood-i that the invention is not limited to the specific details-shown and described, as long as they arevvith-inthe spirit or scope of the claims.

Figure 1 re resents a diametrical section of a kettlebel' embodying my invention.

Fig. 2 represents a perspectivevievv of the handle thereof detached.

Fig. 3 represents a top view ot a portion of the casing thereof.

Fig.. 4: represents: sections the adjacent plates thereof.

Fig. 5 represents a perspective view of a portion of a bar bell embodying my invention. V

Fig. 6 represents a side elevation thereof With Weight members thereon shown in dotted lines.

Fig. 7 represents a transverse section thereof on line 77 Fig.

Fig. 8 represents a side elevation of a dumb bell embodying my invention.

Fig. 9 represents a side elevation of one of the outer plates and end Weights of said dumb bell shown in Fig. 8.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings. I

l designates a Weight of a kettle bell, the same being formed of the series of plates 2 imposed one on the other forming a spherical shaped body Which is contained in a spherical shaped casing or covering 3, the

. f portions of 7 thus,

latter being constructed of hemispherical sections 4" and 5, the diametrica-l edges of which are connected by the lap joint 6,

The upper pole of the casing 3 is depressed as at 7, the side Walls8 of which rise from the depression and extend in angular form to each producing the angu-lar shaped socket or recess 9, 111 What may be termed the top of the Weight.

10' designates the carrying and manipul-ating handleof the kettle bell, the same being. composed of the side arms 11,- the grip I2 at the top thereof, and the collar 13, the latter being at the base of said arms and formed of a plate havingits sides angular as atfl'l l, so as to accord with the side Walls 8 of the angular recess 9 in the casing 3, said collar being. adapted to enter said" recess and have its sides 14: fit Within and be embraced by the Walls 8 of said recess and interlocked therewith. Again the collar forms a strong connection for the inner or lower ends of saidarms 11, andso prevents the spreading of the latter.

,In said collar 13' is a threaded opening to which is screwed the threaded end of the rod or tube 16' which is passed through the opening. 17 centrally in the bottom jvall of the depression 9 in the casing 3, said rod or tube passing also" through openings centrally in the weight plates 2' and being engaged by the nut 18 which isadapted to enter the depression 19 in the bottom pole of the casing and tighten against the well this in connection With the action of the collar 13 in the opposite pole serving to bind the plates 2, the casing 3, and the handle 10, firmly together and produce a compact Weight of which the casing cannot rotate on the handle and vice versa.

As heretofore practised, the collars and recesses therefor have been made of elliptical form, but in such construction as the kettle bells, bars and dumbbells are subjectedto severe usage and the handles and collars are liable to turn in the exercise, the elliptical collars are liable to ride upwardly and outwardly on the elliptical Walls of the recesses and so creep out of the same, thus loosening the collars from the casings and vice versa, and disconnecting and disassembling said parts of the device. This serious defect is remedied by the present construction of collars exterior of angular form and recesses of walls of angular form to receive said collars, thus reliably interlocking the collars in the recess and so preventing the working out of the collars from said recesses during the use of the bells.

The plates are also coupled against separate rotation by means of the tongues 20 on certain of said plates and grooves 21 on other plates, said tongues being adapted to enter said grooves, the effect of which is apparent on reference to Figs. 1 and 4:-

In Fig. 5, 22 designates the handle portion of a bar bell, the same being on the central portion of the rod 23, and intermediate of the angular shaped collars 24, which are bolted or otherwise firmly secured to said rod at the terminals of the handle portion 22 on said rod.

In this case the opposite weights 25, shown in dotted lines have in them depressions forming recesses with angular sides similar to those shown in Fig. 3 to receive said collars 24:, thus interlocking the weights 25 with the relative portions of the rod 23, and vice versa, preventing rotation of either of the same.

In Figs. 8 and 9 I show the application of my invention to a dumbbell in which the outer casing or covering is dispensed with, and the angular recesses 26 are formed in the inner side segments 27 of the series of plates 2, and the angular collars 24: on the handle or grip portion 22 of the rod 23 are adapted to enter the recesses 26 of the segments 27 and interlock with the walls thereof, thus preventing rotation of the dumb bell on the rod 23, and vice versa, it being evident that by this construction the handle portion 22 of the dumb bell is also rendered non-rotatable, it being noticed that the rod 23 which passes through the bodies of the dumb bell is firmly secured by a nut, 28.

Copies of this patent may be obtained for Attention is especially directed to the fact that the weight body independent of the casing thereof is formed. entirely of the plates which when bound together form a complete sphere with the advantages of those of an integral construction of a sphere.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. A weight having a body formed of plates, a casing' therefor, a handle, a rod adapted to be passed through said plates, a tightening device on said rod opposite to said handle, said casing having in its pole a recess with angular walls, and a collar of angular sides on the base of said handle, said collar beingadapted to occupy said recess non-rotatively.

2. In an exercising device of the character stated, a weight-body, and a carrying and manipulating handle therefor, said body having therein an angular recess, and said handle having thereon an angular collar which is adapted to occupy said recess and to be retained therein non-rotatably.

3. In an exercising device of the character stated, a handle, and a perforated collar thereon, the'sides of said collar being of angular form.

4. In an exercising device of the character stated, a weightcontaining casing, a handle, a perforated collar on said handle,-said collar being adapted toenter a recess in said casing and to be secured therein, the sides of said collar being of angular form, and the wall of said recess being also of angular form to accord with the sides of said collar.
